I did mine in my 2005 was fairly straight forward just mainly need a ratchet with a 22mm bolt and a HUGE breaker bar unless your a juice monkey cuz that bolt is damn hard to turn haha. other that that it was a breeze.

and someother small ones to move the belts off

Is the performance gain worth it?

I just put one on this last Sunday. Very easy install. The instructions are straight forward. You definitely need something to extend the length of your breaker bar though (that bolt is friggin tight). Other than that this was the easiest mod yet, except for the dead pedal of course.

Ahh, but the question is, how do you keep the engine from turning over as you remove the bolt?

Put the car in 5th gear, and have someone depress the brake pedal. That should link the whole driveline. When the brake pedal is depressed, the whole system from the rotors to the crankshaft will be locked, allowing you to remove the bolt.

Install is the opposite of removal.

Simple install, and the gains are there somewhere. Whether or not it makes anymore power isn't for me to say, but the revs sure liked the pulley. Imho, a great drivability mod.

When you get a crank pulley make sure you get a lightened pulley and not an underdriven one. I put an underdriven pulley on my gf's car and let me tell you what a pain in the ass. The windows roll up and down slower, the heater fan runs slower at idle and the lights dim at idle as well. I have the lightened one on my 06 wrx and you get none of that.

I had the lightened underdriven pulley on my old car, never again!

The light dimming alone was a major PITA!
